Two angles are supplementary. One angle is 16° less than three times the other. Find the measures of the angles

Ivan

Answer:

Step-by-step explanation:

x and y are supplementary angles, so their sum is 180°.

x+y = 180°

x is 16° less than three times y

x = 3y - 16°

(3y-16°) + y = 180°

4y = 196°

y = 49°

x = 3y-16° = 131°

If m angle B=m angle D=41, find m angle C so that quadrilateral ABCD is a parallelogram

Charra [1.4K]

ANSWER

139°

EXPLANATION

One of the interior angle properties of a parallelogram is that adjacent interior angles are supplementary.

This means that, the adjacent interior angles add up to 180°.

$m \angle \: B = m \angle \: D = 41$

Then

$m \angle \: C + m \angle \: D = 180 \degree$

$m \angle \: B + m \angle \:C= 180 \degree$

$\implies41 \degree + m \angle \:C= 180 \degree$

$\implies m\angle \:C= 180 \degree - 41 \degree = 139 \degree$

False

(5,5)
y < x + 3
5 < 5 + 3
5 < 8 (correct)

(5,5)
y > -2x - 1
5 > -2(5) - 1
5 > -10 - 1
5 > -11 (correct)

so (5,5) is a solution..and there are many more
